Granted: 2008-04-22
Abstract: This invention is directed to compositions and methods containing physiologically stable compounds of butyric acid salts, derivatives of butyric acid, or combinations thereof, for the treatment of neoplastic and other diseases and disorders including leukemias, lymphomas, sarcomas, carcinomas, squamous cell carcinomas, neural cell tumors, seminomas, melanomas, neuroblastomas, germ cell tumors, undifferentiated tumors, mixed cell tumors, metastatic neoplasias, neoplasias derived from pathogenic infections and other malignancies. Butyric acid derivatives include analogs homologs including next adjacent homologs and compounds based on a part of the butyric acid moiety. These compositions are useful prophylactically and as a treatment for directly eliminating transformed cells by inducing cellular differentiation. These same compounds also indirectly eliminate transformed cells by reducing the expression of MHC and non-MHC antigens of the surface of transformed cells which enhances their identification and subsequent removal by the patient's immune system. In addition, these compositions are useful for decreasing multi-drug resistance activity of the cell which, in conjunction with conventional chemotherapy, results in greater concentrations of chemotherapeutic agents within the cell, thereby enhancing there effectiveness, and for the treatment and prevention of gastrointestinal disorders such as colitis, inflammatory bowel disease, Crohn's disease, and ulcerative colitis.

Title: Pre-assembled electrical panel bonding screw
Inventor: ROSE WILLIAM E
IPC: H02B1/015
Filed: 1998-03-25
Granted: 2007-12-04
Abstract: A bonding screw is pre-assembled in a distribution panel in a non-bonding position that does not bond a neutral bar within the panel enclosure to the enclosure wall. This allows an installer of the panel to select between the option of maintaining the bonding screw in the pre-assembled non-bonding position and the option of positioning the bonding screw from non-bonding position to a bonding position. A basepan is disposed within the enclosure between the neutral bar and the enclosure's back wall. The non-bonding position is defined by the screw shank thread having a threaded engagement with a through-hole in a basepan, the head of the bonding screw being spaced from the neutral bar, and the shank of the bonding screw being spaced from the enclosure's back wall. The bonding position is defined by the head of the electrically conductive part being disposed against the neutral bar and the shank being threaded into an extruded hole in the enclosure's back wall.

Abstract: A holder for radially sawing a log has a plurality of independently movable arms or fastening devices that are adapted to hold logs at both ends for longitudinal sawing. The holder therefore enables complete cuts to be made along the full length of the log at the required depth for integrated production of a range of timber products, such as backsawn or quartersawn boards, trapezoidal sections or sector wedges. The arms allow cuts to be made along the radii of the sectors of the log to form individual wedges. The holder furthermore holds the wedges after being sawn, releases individual wedges on demand, and adjusts for logs with uneven ends.

Abstract: A non-thermal vapour extraction method for the recovery of hydrocarbons from deep, high pressure hydrocarbon deposits, either previously exploited by cold flow or virgin deposits that may be underlain by active aquifers is described.  The method, termed RASD-Vapex, utilizes a light hydrocarbon solvent vapour in a tailor-made mixture with reservoir natural gas so that the solvent dew point is adjusted to the reservoir conditions of temperature and pressure. The solvent is selected typically from the group of ethane, propane and butane and may be used by itself or combined in a solvent mixture. The surface facilities in which the dewpoint is adjusted to downhole conditions consist of a solvent stripper, separator, solvent injector, dew point controller, pumps and a control unit. The spent tail gas is analysed in-line for the active solvent component, enriched with the required amount of recycled solvent and reintroduced into the reservoir as an injection gas with solvent at its dew point. Both the recovered solvent and free gas are being continuously circulated through the reservoir. The extraction is a continuous process and is accomplished by either employing pairs of parallel horizontal injection/production wells that are spaced laterally apart and alternate or by converting existing vertical or inclined cold production wells into injectors and adding horizontal production wells. The horizontal producers are in communication with the reservoir fluids through slotted liners. The initial injectivity and a large solvent-oil mass transfer area required for an economically viable operation are accomplished by utilizing high permeability zones of the reservoir, such as fractures, channels left behind after cold flow production or aquifers. The horizontal producer may be located at the bottom of the pay zone just above the aquifer and the active aquifer between injection wells may also be receded deeper into the reservoir to control water production. The concept of reservoir adjusted solvent dew point makes this environmentally friendly extraction method amenable to a wide range of watered out reservoirs that have been abandoned, although only about 10% of the original oil in place had been recovered.

Title: Nuclear magnetic resonance logging with azimuthal resolution
Inventor: GOSWAMI JAIDEVA
IPC: E21B49/00
Filed: 1999-05-04
Granted: 2003-12-23
Abstract: The present invention relates generally to an apparatus and method for obtaining an azimuthally resolved nuclear magnetic resonance measurement of an earth formation traversed by a borehole. The measurement can be made while drilling or using a wireline tool. A receiving rf antenna having a non-axisymmetric response pattern is used to obtain the azimuthally resolved nuclear magnetic resonance measurement. The antenna employs axial currents which excite an azimuthally oriented rf magnetic field.      For this situation, the static magnetic field is either radial or axial in its orientation. The antenna generates a relatively long, in axial extent, region of generally uniform static field magnitude and polarization in the formation. The present invention facilitates low profile antenna configurations that can permit dispensing with the reduction of the inner diameter of the drill collar at the rf antenna location.

Abstract: The press comprises a first generally-horizontal link (L1) below a second generally-horizontal link (L2). A third link (L3) extends down from the second link to the first link and carried a press tool (70) with a generally downwardly facing working surface. A fourth link (L4) is arranged to be driven by a first mechanism (DS, M2) to push the second link and thus the press tool generally forwards from a horizontally retracted start position to a horizontally advanced initial pressing position, after which the first mechanism is arranged to hold the position of the fourth link. A second mechanism (DS, C, L5) is arranged, when the position of the fourth link is being held, to pivot the first link to drag downwards the third link and thus drag the press tool generally downwards from the initial pressing position to a vertically lower final pressing position.
